How to Remove Black Mould from Bathroom Ceiling: 1-Minute Fix: Say Goodbye to Mould in Your Bathroom

Dealing with black mould on your bathroom ceiling is not only an eyesore, but it can also present serious health concerns if left untreated. This mould thrives in areas with high humidity, low ventilation, and repeated moisture exposure—just like your bathroom. To effectively remove black mould, start by ensuring your safety: wear gloves, protective eyewear, and a mask to avoid inhaling harmful spores. Next, ventilate the room by opening windows or running an exhaust fan.

Prepare a cleaning solution using either a commercial mould remover, a mixture of one part bleach to three parts water, or white vinegar for a less harsh alternative. Using a spray bottle, apply the cleanser generously to the affected areas on your ceiling. Let it sit for at least 10-15 minutes to penetrate the mould. With a non-abrasive sponge or brush, scrub the spots gently to remove visible mould, then wipe down the area with a clean, damp cloth. Rinse and repeat if necessary for stubborn patches. Once done, dry the ceiling as thoroughly as possible and keep the bathroom ventilated to prevent future growth.

As an interior designer, I routinely encounter clients with persistent bathroom mould issues. Beyond simple remediation, it’s essential to address the true source—often inadequate ventilation or a flawed room layout. Modern solutions like using a specialized bathroom design tool can help you reimagine your space for improved airflow, better placement of exhaust fans, and moisture-resistant materials, creating a healthier and more visually appealing environment.

Tips 1:

Regularly inspect and clean bathroom ceilings, especially after steamy showers. Use anti-mould paint when possible, and make sure to always run your ventilation fan during and after using the bathroom to discourage future mould growth.
